BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a packaging box. More particularly, the present invention relates to a packaging box with the concept of environmentally friendly protection.

2. Description of the Related Art

With the rapid development of electronic technologies, most electronic products have powerful and multifarious functions. However, from the other aspect, these electronic products have precisely manufactured structures that when these products are transported from place to place, they are vulnerable to damages because of collision, vibration or other external factors. Thus, the electronic products are generally packed inside a packaging box. Through the protection of the packaging box, damages to the electronic products can be significantly minimized.

A conventional packaging box normally includes a box, multiple lower frames and multiple upper frames. Typically, the upper frames and the lower frames are fabricated using polyethylene (PE). When multiple electronic products are packed inside a conventional packaging box, the respective sides of each electronic product are embedded inside one of the lower frames and one of the upper frames. The lower frames and the upper frames are positioned inside the box and aligned in parallel at the bottom and top portion of the box. Hence, through the interference between the outer edges of these frames and the inner edges of the box, the packaging box is able to fasten the electronic products firmly inside the box. When the packaging box is subjected to an impact, a vibration or some external factors, the frames can absorb most of the impact. Therefore, the conventional packaging box can protect the electronic products packed inside the box and minimize all kinds of possible damages.

Although the aforesaid packaging box can protect the packed electronic products inside the box, the polyethylene frames used inside the box is not considered environmentally friendly. With the trend and desire for environmentally friendly products in our society, a packaging box that incorporates the concept of environmental protection is in great demand.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

FIG. 1 is a perspective view of an assembled packaging box according to one embodiment of the present invention. FIG. 2 is an explosion view showing the components constituting the packaging box shown in FIG. 1. To make the profile of the components inside the packaging box 100 clearly, the profile of the box 200 and the partition panel 400 are shown in dashed lines. As shown in FIGS. 1 and 2, the packaging box 100 mainly comprises a box 200 and a first frame 300. The first frame 300 is disposed at the bottom of the box 200. Both the box 200 and the first frame 300 are fabricated using paper material, for example.

FIG. 3 is a top view of an embryonic panel for forming the first frame shown in FIG. 2. As shown in FIGS. 2 and 3, the first frame 300 is formed by folding an embryonic panel 300 a. The first frame 300 mainly includes a bottom panel 310, a pair of flaps 320 and a pair of tabs 330. The flaps 320 are connected to the opposite sides of the bottom panel 310. There is a first folding line F1 at the junction between each flap 320 and the bottom panel 310. In the present embodiment, the first folding lines F1 are substantially parallel to each other, for example.

Each flap 320 has multiple inlaid openings 322, a second folding line F2 and a third folding line F3. These inlaid openings 322 are disposed along the direction of extension of the first folding line F1. Each inlaid opening 322 is suitable for housing one part of an object P. The second folding line F2 is tangent to one side of these inlaid openings 322. The third folding line F3 is tangent to the opposite side of these inlaid openings 322. The distance from the bottom panel 310 to the second folding line F2 is greater than that to the third folding line F3. Furthermore, the second folding line F2 and the third folding line F3 are substantially parallel to the first folding line F1, for example.

Aside from having a second folding line F2 and a third folding line F3, each flap 320 may include a fourth folding line F4. The fourth folding line F4 is disposed between the second folding line F2 and the third folding line F3 and crosses over the inlaid openings 322. The fourth folding line F4 is substantially parallel the first folding line F1. Obviously, aside from having a single fourth folding line F4 between the second folding line F2 and the third folding line F3, each flap 320 in the present embodiment may further include multiple fourth folding lines F4 so that the flap 320 can have other configurations.

Furthermore, each first flap 320 can have a first wing plate 324. These first wing plates 324 protrude from the flaps 320 on the side adjacent to the first folding line F1. These first wing plates 324 are disposed between the bottom panel 310 and the bottom wall of the box 200. With this arrangement, the first wing plates 324 can absorb part of the energy and prevent the object P from being damaged when the packaging box 100 is subjected to an impact, vibration or actions due to some other external factors. In addition, because the first wing plates 324 are disposed between the bottom panel 310 and the bottom wall of the box 200, a space is created between the bottom panel 310 and the bottom wall of the box 200. Hence, filler material can be inserted into this space so that the object held inside the packaging box 100 is even better protected. Obviously, aside from accommodating filler material, this space can be used for putting other objects as well.

Aside from forming the space between the bottom panel 310 and the box 200 through the first wing plates 324, the space can be formed by disposing a second wing plate 326 on the either side of the first folding line F1 adjacent to the bottom panel 310. Because the function of the second wing plate 326 is identical to the first wing plate 324, a detailed description is omitted.

The tab 330 is connected with a corresponding flap 320 along the second folding line F2. Furthermore, the tab 330 is fixed to the bottom panel 310. In the following, the mechanism for fastening the tabs 330 to the bottom panel 310 is described in more detail. In the present embodiment, each tab 330 has a cut opening 332 and the bottom panel 310 has a plurality of fixing plates 312. The fixing plates 312 are disposed to correspond with the respective cut openings 332. Furthermore, one side of each fixing plate 312 has a fifth folding line F5. Thus, each fixing plate 312 is suitable for forming an interference fit with a corresponding cut opening 332 through the outer edge of the fixing plate 312 so that the tab 330 is fastened to the bottom panel 310. Obviously, aside from having a single cut opening 332 in each tab 330 on one side adjacent to the third folding line F3, a cut opening 332 can be formed on the opposite sides of the tab 330 adjacent to the third folding line F3.

On the other hand, beside the disposition between the cut opening 332 and the fixing plate 312 described in the paragraph above, the fixing plates 312 can be disposed on the respective tabs 330. Meanwhile, the cut openings 332 corresponding to these fixing plates 312 can be formed on the bottom panel 310. In other words, the disposition of the tabs 330 and the fixing plates 312 are simply reversed. Hence, the detailed description is not repeated.

As shown in FIG. 2, the packaging box 100 disclosed in the present embodiment might further include one or more partition panels 400 beside the box 200 and the first frame 300. The partition panel 400 is also fabricated using paper material and disposed inside the box 200 located between the sidewall of the box 200 and the first frame 300, for example. The partition panel 400 mainly comprises a main body 410 and two partitioning wing plates 420. The partitioning wing plates 420 are connected to the opposite sides of the main body 410. Furthermore, there is an eighth folding line F8 at the junction between each partitioning wing plate 420 and the main body 410. These partitioning wing plates 420 are disposed between the sidewall of the box 200 and the first frame 300. When the packaging box 100 is subjected to a collision, vibration or action due to some external factors, the wing plates 420 can absorb most of the energy so that damage to the object P is minimized. Furthermore, because the partitioning wing plates 420 are disposed between the sidewall of the box 200 and the first frame 300, a space is created between the bottom panel 310 and the box 200. Therefore, the present embodiment permits filling the space with filler material so that the object enclosed within the packaging box 100 is even better protected. Obviously, aside from filler material, the space can be used to accommodate some other objects.

It should be noted that a packaging box 100 with two partitioning panels 400 is used in the present embodiment. However, this should by no means limit the scope of the present invention. The number of the partition panels 400 used can be increased or decreased according to the actual requirements.

In addition, the packaging box 100 disclosed in the present embodiment may further include a second frame 500 beside the box 200 and the first frame 300. The second frame 500 is also fabricated using paper material, for example. The second frame 500 is disposed inside the box 200 and located near the top wall opposite the bottom wall of the box 200. The second frame 500 has a structure identical to the first frame 300. Obviously, the present embodiment may also include one or more partition panels 400 disposed between the sidewall of the box 200 and the first frame 300 and the second frame 500, the detail of which is not repeated here.

In the present embodiment, the box 200 has an opening 210, for example. Furthermore, the packaging box 100 further includes at least a cover panel 600. The cover panel 600 is connected to the box 200 for sealing the opening 210.

In the following, a description of the steps for packaging an object P inside a packaging box 100 having the structure disclosed above is provided. FIGS. 4 through 7 are perspective views showing the steps for packing an object inside the packaging box of the present invention. To make the profile of the components inside the packaging box 100 clearly, the profile of the box 200 and the partition panel 400 are shown in dashed lines.

First, as shown in FIG. 4, the first frame 300 is disposed inside the box 200 and placed at the bottom of the box 200. Then, as shown in FIG. 5, the object P is inserted into the inlaid opening 322 of the first frame 300. After that, as shown in FIG. 6, the partition panels 400 are disposed between the first frame 300 and the sidewall of the box 200. Next, as shown in FIG. 7, the second frame 500 is put into the top of the box 200 along the direction D1 and inserted the parts of the object P away from the first frame 300 into the inlaid openings 322 of the second frame 500. Finally, the cover panel 600 is flipped over along the direction D2 to seal the opening 210 and form the packaging box 100 as shown in FIG. 1.

In summary, the frame is formed by folding an embryonic panel and the packaging box is fabricated using paper material. Hence, the packaging box disclosed by the present invention not only saves the quantity of the material but also uses material that is friendly to the environment. Accordingly, the present invention meets the demand of environmental protection.
